New interferometers as the VLTI, the Keck-I and CHARA along with their sophisticated instrumentation have provided new levels of accuracy, spectral resolution and access to various spectral bands from the optical to the thermal infrared. Investigations are now enabled on a wealth of astrophysical sources with unprecedented levels of angular resolution and sensitivity, producing a considerable body of new, exciting scientific results.

Celebrating the completion of the first phase of the VLTI development, the organisors of the ESO workshop "The Power of Optical/IR Interferometry,"...
